Comparison of ProSeal Laryngeal Mask Airway to Laryngeal Mask Airway Supreme

Milton S. Hershey Medical Center52 enrolled

Overview

Laryngeal mask airway is a widely used device in routine anesthesia for airway management during surgery. It consists of a tube with an inflatable cuff that is inserted into the mouth after induction of general anesthesia. The Proseal Laryngeal mask airway and the Laryngeal mask airway Supreme are two variants of the Laryngeal mask airway. The laryngeal mask airway Supreme is a newer version of the laryngeal mask airway. The research is being done to compare two variants of the laryngeal mask airway: the Proseal laryngeal mask airway and the Laryngeal mask airway Supreme. This study will determine if the newer model, the Laryngeal mask airway Supreme, is easier to insert and is better positioned than the older model, the Proseal laryngeal mask airway. Both models are approved for use by the FDA, and are routinely used to assure the airway during general anesthesia.

Outcomes

Primary Outcomes

Insertion Time

The insertion time will be the measured time that it takes the anesthesiologist to insert the airway and verify ventilation of the patient's airway. Data reported will be time in seconds ± the standard deviation.

Time frame: During intubation of the patient

Secondary Outcomes

Insertion Success Rate

Insertion success rate will be reported as the number of patients for whom the airway device was successfully inserted and ventilation was verified.
